In a patient with a tibia/fibula fracture showing symptoms of compartment syndrome, what should be done next?

Measuring intracompartmental pressure is the appropriate next step in the management of suspected compartment syndrome following a tibia/fibula fracture. This condition arises when there is increased pressure within a muscle compartment, which can lead to tissue ischemia and necrosis if not addressed promptly.

By measuring the intracompartmental pressure, healthcare providers can confirm the diagnosis of compartment syndrome. Normal pressures range from 0 to 10 mmHg, while values greater than 30 mmHg are typically indicative of the syndrome and warrant urgent intervention.

Assessing pressure not only aids in determining the need for surgical intervention but also helps differentiate true compartment syndrome from other causes of similar symptoms such as swelling or hematoma.

In contrast, pain medication administration may temporarily relieve discomfort but does not address the underlying issue and does not provide diagnostic information regarding compartment syndrome. While a fasciotomy is the definitive treatment for compartment syndrome, it should be performed only after confirming the diagnosis; therefore, it is not the immediate next step. Similarly, ordering a CT scan does not provide timely information on compartment pressures and could delay vital treatment.
